2009 vantage sport shift inconsistency
Discussion
Hello my name is Brian and I live in the USA . I was Looking at several vehicles before I picked the Aston and I wanted to be different and always loved the look of the astons.
I feel like I did everything correct and did all the precautions of getting the right car. I had the dealer do an inspection and only a couple of minor things came back and one thing I asked him several times was how was the clutch and they said it was OK.
I bought the car and start driving the car a little bit and noticed as I get higher in the RPM range the car almost acts confused? When you're in gear and you shift there is sometimes a delay before it shifts. On other occasions it shifts fast and firm. It also seems like when you shift in the higher RPM range it sometimes can Have the delay and other times it can be right on and firm.
The dealer did a readout of the gearbox and told me everything was correct. There are several values in there that I am not sure what they exactly mean. The clutch does not appear to be slipping but I am comparing this to the other manual cars that I have owned. I drove it on the highway at low speed in high gear and stood on the throttle and it does not slip. Also if I put the car into drive mode and rev it out it seems like it is also pretty good and firm. It seems once you try to get up in the higher rpm's it doesn't want to go into gear quickly it will usually go in gear but it takes a few seconds and it acts is like the car is confused and does not know what to do.
I know the original owner drove the car very easy so I have been doing clutch learns several times to try to get it fixed. My confidence in the dealer is minimum because I asked him about this and they said it was OK. I have an independent shop and he is recommending we change the fluid with the mobile 1 with a additive and try that first.
Any thoughts or ideas? it's very disappointing that I bought my dream car drove it for one day and has been in the shop for a week ... At this point I really feel like I want to sell it but then I look at the car and really love it.

Car is currently at a independent tech. I lost faith in the dealer I paid to do a ppi and they missed things like marker lights being out! I bought there car and drove it for two days and it has been in the shop since. Very disappointing that I finally get my dream car and after doing all the research and getting a good bill of health from the dealer I am stuck with this. He was going to swap out the gearbox oil today and add a additive he said. I am skepticle but I guess I will let him try that first.
I will mention the brake switch... He is possibly thinking the magnetic gear selector sensor? The other day when he was testing the car the car shifted to the next gear but the indicator did not change. This also happen to me this morning. So that sounds like a possibility? so basically both him and myself hit the paddle to shift to the next gear the car did shift to the next gear but the indicator stayed at the previous gear selection. It through a quick code I bumped the paddle and it matched the indicator to the appropriate gear . It's like it's confused... So I guess that is possibility? Anyone experienced this sensor fault before?

mike thanks! I actually just realized possibly you are the connection Greg in Arizona has been talking with? I am awaiting some numbers from him to try and figure this out with software. I was wondering if the sensor was worth a try. It's driving my crazy!! The other night the car was just about perfect shifting and working well. The next day it went to crap again... Gearbox shifted but the dash cluster did not change. No funny noises and the car runs and drives great even at stops and reverse. Car was shifting At almost 7k Rpms with no problem. Greg has been a great person to deal with!! Below is what the dealer gave me, the first owner drove the car like a baby so the errors may not be showing up in that picture. You may of seen this already...

Still dealing with this nightmare! Car is at dealer now with trans out. They say sensor and magnet looks fine? Mike what are your thoughts on the posted info they sent? I was also told by them that snapshot tells that the clutch is fine. As I dig deeper there is another section in the software that shows in depth clutch values as I thought.

I am stuck between a rock and a hard place as my dealer options and repair facilities local to me are minimum. The trans is out and the dealer says the mag sensor appears to be ok? They want to change the sensor on the torque tune that reads the shaft speed. I stopped at the shop one day and they were going to put the trans back in the car. So I asked them we are about two hours away from actually seeing the clutch why don't we pull it out? They agreed and out it came. The clutch does appear to be worn and has a high spot on the outside of the flywheel and the flywheel shows signs of heat. ( I will send you the pics of you have a email) car is going back together this week and I hope it fixes my problems. I have owned the car for months and it has been on the shop the entire time. The one thing that I keep thinking about is the times I have shifted the car and the gearbox makes the shift fine but the dash reads the previous gear. It then throws a gear fault message until you bump the paddle o match the current gear. Would the clutch make the car do something like this?
